LEGO Wheels Diameters & Weights Chart

April 12th, 2014 Leave a comment Go to comments

A new tool is available: chart with sizes and weights of some of the most popular LEGO wheels.

Available at wheels.sariel.pl, the sizes & weights chart is intended to help you when choosing your wheels. I often find myself wondering which wheels are best suited at a given scale, and I’m not anywhere near my workbench to check the size, and when building high-performance models I sometimes try to find out if there is a lighter wheel of the same size. This chart is supposed to help with questions like that. It includes all the types of wheels I own, so some are missing, sorry.

The wheels are ordered from smallest to biggest ones, and if their sizes are identical, then from lightest to heaviest ones. The images of the wheels work as links for Bricklink catalog, to help you find the wheels easily. All sizes and weights were carefully measured by me, and I’m surprised to see they are sometimes quite different from the Bricklink catalog’s data. While I was trying to do my best to get most accurate data possible, I can’t guarantee it’s absolutely correct. Several wheels of the same type can vary, they may have been produced at different times, in different batches, by different machines. Still, I hope this tool is helpful to you, and I will be trying to update it as I get more wheels.

    Are there any wheels that are able to be turned at the center as in a real car? I’ve seen models that look like they turn at the center. All I know of are wheels that only turn off center and require large spaces for them to turn with out hitting anything. This problem especially arises when you use portal hubs. Thank you

    Hi. Nice chart. It would be nice to add tracks with sprockets. Such diameters would be useful when setting up EV3 lejos classes, for example: http://www.lejos.org/ev3/docs/lejos/robotics/navigation/DifferentialPilot.html

    And here’s another idea for an amphibious vehicle: build an offroad vehicle with big bumpy tires and high ground clearance and somehow connect one or serveral plastic bags to the underside which were closed everywhere apart from a small hole with a pneumatic tube in it. So the plastic bags could be inflated and reinflated by a pneumatic system. The advantage: inflated they would make the vehicle swim and reinflated they wouldn’t affet the ground clearance. The propulsion could be a set of rudders and propellers folded into the water while floating and out again on land.So such a vehicle would be as good on land as a not-amphibious one.

    Why the compressor? If you connected both inlets/outlets of the airtanks to a valve which is kept closed all the time the air would stay inside all the time.

    The power puller tires appear to be 62 mm wide.

    Very nice list. I think it would be great if there would also column with size/weight ratio, so maybe sometimes smaller wheels are better performing than larger wheels.

    Oh. Hmm. The price wouldn’t be a problem if you only needed like 5 of them or so. People are willing to cough up $100 for a set of Power Puller wheels. Are they?

    This is a well known idea. The only problem is that you would need tens of airtanks, and they’re kind of expensive.

    I actually thought of another idea! What if I had a few pneumatic air tanks on the underside, with a pneumatic compressor in the trunk or wherever there’s enough space, to fill them up with air and keep it buoyant?

    I like to play in 1:16 for trucks i.e., and there wheel width co-determines via steering lock the maximum chassis width, which was a challenge indeed designing my 8×8.

    @Witherley Yes, why not? Serveral hulls would also increase stability.

    Thanks for the info! I had a bit of a play in LDD and noticed that the large boat hull makes it look a lot worse and harder to cover up. Do you think it would be a good idea to get a few smaller hulls and securely attach them underneath a normal chassis with high-up electronic parts, to reduce their visibility?

    I’m saying it requires more torque than smaller wheels.

    Hey witherley, here,s my idea about an amphibious vehicle :building a tank with the large LEGO chains and a boat hull as a chassis so it can swim. Then attach one technic beam per track piece and drive everything with big (probably XL?) Motors via the RC unit. To me that would provide easy steering and good grip on land and some serious thrust on water. Also getting from Land to water would be just as simple and safe As at sariels vehicle

    Sariel :
    You don’t see any because they are very hard to find. And large wheels require much more torque to drive.

    When you say it requires large amounts of torque to drive, are you talking something like XL motors here? I’m just gathering information.

    And how easy are the black ones to find. FOr some reason I never see any on Bricklink.

    I’m thinking of making an amphibious car like your LIME Mk. II, but with proper steering and everything. Also having big wheels would increase the speed of your vehicle because of its increased circumference meaning it covers a larger length with every rotation. Also, do larger wheels increase the off-road and crawling capability of a vehicle?

    @Tobias Stanisfugl
    I don’t know, is width really important?

    Depends on what you want to do with them.

    DO you think it would be a good idea to get some Exo Force wheels (the huge green ones) ?

    Thank you so much for your small practical Charts!

    Suggestion to add the width, but labour seems closed here?

    These wheels do not fit on regular Lego (and the motor does not to)

    I don’t have these wheels.

    What about the wheels from the 8675 set? Also, what’s the motor that drives it?

    I think if you ask for the missing wheels, if people are willing to fill in the gaps, you will have it complete in no-time.
